Appueation'lea Aprii 1o, 1917. serial No. 160,947.

To all 1whomz'zf mayfconcem:

Be it known that I, ALBERT l/VILTZ, a citi- 4zen of theUnited States, residing at Addy, -in the county. of Stevens and State of `Wash have invented certain new and 4useful Improvements in Fluid-Pumps, ofwhich the following is a specication.

This invention relates to new and useful improvements in fluid pumps and the principal object is to provide a device of'this character which will facilitate the removal of fluid contents vfrom barrels, shipping Ftanks, drums, etc.

A further lobject ofthe invention resides l5 'in providing a device whereby virtually the entire contents of such vessel may be removed by means of one operation.

A further object of the invention resides Vin providing a device wherein I am enabled by use of the same implement to provide for air-tight connection with tanks, drums or barrels provided with various sized openings for the removal of their liquid contents.

With these and numerous other objects in view my invention consists in the novel features of construction, combination andarrangement ofparts aswill be hereinafter referred to and more particularly pointed out in the-specification and claims. .Y

In the accompanying drawings forming va part of this application,

Figure 1 "is a view of section.

Fig. 2 is a plan view thereof.

Fig. 3 is a partial view of the base.`

Fig. 4 is a partial cross section through the base disclosing the valve closure means for preventing the escape of air from the vessel to which the pump is attached.

In describing my invention I shall refer to the drawings in which similar reference characters designate corresponding parts throughout the several views and in which 1 designates a base member provided to support upstanding cylinders 2 in which are mounted pistons 3 provided with stems 4 slidably mounted in a guide bushing 5 which is a part of the handle supporting frame 6. 6 is designed to embody the cover plates 7 of the cylinders 2 and be secured thereto by means of bolts or screws S. An upstanding arm 9, bifurcated and provided with openings 10, serves to support an operating beam 11' and a pin 10 serves for pivotal engagement within the bfurcated portion 9, The

my pump partly in Y beam 411 consists ofran upstanding .leverenrgagmg stub 12 and out-spreading -arms 13 and 14 each provided with vcurvilinear slots 15 and 16, respectively. Upon the ends .of

Vthe piston rods 4 are eye-members 17 provided' for pin `connection to the beams 11 and being loosely connected to the slots V15 and 16 for operation therein.

Provided for engagement with the stub :12 ifs-a ,handle member. 18-provided with a hole 19 bywhich it may be disposedv upon a nail or hook out of reach of mischievously inclined '.children. At 2O Iprovicle :the .edges .of the handle with beveled portions which are intended to engage with upstanding lu'gs Aprovided onI the basel. .This providesv a wrench engagement of the handle with the base and will be used in adjusting a pump to a fluid container. Upon the lower portion ofthe base are threaded bosses v22 and 23 of various sizes for engagement with the standard tanksor drums that .are used in, shipping liquids throughout the country and lextending below the threaded boss 23 I provide a tapered threaded plug .24 provided for use upon wooden containers such as the usual type of barrel wherein it is necessary to fit the Apump of my construction yin the bung lthereof and tightly engage it thro-ugh means of the threads therewith to prevent a leaki age of air therefrom.

In order to secure-leverage for adjusting my pump in the various containers necessary, I make use of the handle as above fdescribed, and by this means secure sufficient leverage. In operation of the pump, it is desired, at times, to stop the iow and for this purpose I provide a winged plug 25 threadably secured in the base 1 and engaging with the passage extending therethrough. As the pump of my construction is designed to force air under pressure within the tank and by means of the pressure expel the liquid contents thereof, it will be evident that by unscrewing the plug 25 and neutralizing the pressure within the tank I am enabled to stop the flow. About centrally of the base member I provide a tubular passage 26 and upon the upper end thereof provide a supply hose 27 with a liquid-tight connection therewith. Upon the bottom and eX- tended end of the tubular passage I mount a similar hose 28 of sufficient length to extend to the bottom of a drum or other container. In some types of containers the closure is in the end and others in the sides, and it is necessary that I extend the hose connection 28 sufficiently to overcome the extreme conditions that have to be met. I provide a serrated end to the hose 28 so that it will not become closely engaged with the sides or bottom of the tank to prevent a flow of fluid therethrough when pressure has been placed in the tank. Y

After attaching the device of my construction to a liquid container by Working the handle 18 I am enabled to pump a pressure of air upon the liquid contents to expel same through the hose 28 and through the passage 26 and hose 27 to the desired point of use. To insure against leakage of the air pressure when the'pump is at rest I dispose lin the air passage 29 a check valve 30 of the usual plunger type and prefer that this check valve be similar to those in use in tire air tubes and the like so that replacement may be easily made.

From the foregoing it will be seen that I have provided a simple, inexpensive and efH- eient means for carrying out the objects of the invention, and while I have particularly described the elements best adapted to perform the functions set forth, it is obvious that various changes in form, proportion and in the minor details of construction maybe resorted to, without departing from the spirit or sacrificing any of the principles of the invention.

I claim Y l. In a fluid pump, a combination with air pressure cylinders, of a supporting base therefor provided with means for attachment to barrels, drums or tanks having a variety of sized openings therein, a fluid outlet through said base, connections therewith, one extending downward into the receptacle and one leading upward and to the point of delivery, plungers in said cylinders, and operating means therefor.

2. In a fluid pump, the combination with air pressure cylinders, of a supporting base therefor provided with stepped threaded Vmeans for attachment to containers having various sizes of openings, a fluid outlet through said base, a hose connection extending into the barrel and another extending upward for engagement with a supply hose, plungers in Vsaid cylinders, andA operating means therefor consisting of a beam with slotted engagement with the plungers and pivoted at its center, an upstanding handle engaging stub thereon and a'handle'fitting thereto, and said handle providedV with means for engaging the base for securing said base to a container.

3. In a fluid pressure pump, the combination of air pressure cylinders, plungers therein, means for operating same, of a base litted for attachment to various types of fluid containers, air passages leading from the cylinders and leading into the interiorof the` container, a check valve interposed therein to prevent back flow of air, flexible hose connection fitted to the under-side vof the base and extending into the container, said means provided with a serrated end, and means on the upper'side of the base for the attachment of a supply hose.

l. In a fluid pressure pump, the combination with air pressure cylinders and operating means therefor, of a base supporting said cylinders and provided with threaded means for engaging containers of various kinds and one of said means consisting of a threadedtaper for adjusting said pump to a bung hole of a Wooden barrel, and means for sealing it therewith.

In testimony whereof yI ailix my signature.
